That truthfully depends on the transmitter's transmitting power, height of the transmitting antenna and the terrain.
I would look to the antenna system, a stronger signal from the antenna is needed for a digital set than for the old analog sets. Try aiming the antenna. Raising the height it or better yet install a new higher gain with a amplifier and new down lead.

Since the ionosphere have different types of layers namely D,E and F layers. So when a pulse transmitted from transmitter it get deflected or we can say reflect by these different layers and reaches to the receiver.Thus the path followed by the pulse is the Actual path.The distance between the highest point of actual path and the earth surface is called Actual height.When a short pulse of energy sent vertically upward and traveling with the speed of light would reach taking the same two rays travel time as does the actual pulse reflected from the ionospheric layers. that height is known as Virtual height of an antenna.
while receive is not that important, transmit/receive is proportional here is the formula 234 divided by the frequency in Megahertz= length in feet 93.1/234=2.51 feet or 30 inches
Height, direction, antenna type and down lead are major factors in receiving a good TV signal to the TV set.
trigonometry
The height of the Empire State Building's antenna is 204 feet.
Antenna height is defined as the ratio of the induced voltage to the incident field intensity for maximum reception. H=Voc/E m
Nothing, the ball is still in, unless the ball hits the antenna. If the ball hits the antenna at any point. The ball is called out.
A better simple approximation would be two antennas separated by twice the distance of the single antenna to the ground.
effective height of half wave dipole antenna
it depends on the location of the tower of globe>>
low profile means small height and weidth...
For horizontal antennas operating below 30 MHz the optimum height is half a wavelength, so the height in metres would be 149.9/Frequency in MHz.
That depends on a number of factors. Antenna height both receive and transmit. Transmitter power and antenna gain. About 15 miles max.
The antenna on the Eiffel tower is 24 meters tall.
